In the last figure, RODR is updated directly by writing to this register when the 16-bit Timer 2, 3
interrupts occur. As shown, the REMOUT waveforms are different according to CEN bit.
The function of “rdpe_disable_mode_init” is a prerequisite for RDPE disable mode.
void rdpe_disable_mode_init()
{
RMR = 0x08;
RDRH = 0xFF;
RDRL = 0xFF;
RODR = 0x00;
RMR = 0x00;
}
11.7.7 Carrier Generator Interrupt
When RDC counter reaches to RDRH or RDRL register, an interrupt can be requested. As the RDC
counter functions when RDPE bit is ‘1’, the interrupt is requested only when RDPE bit is ‘1’. Even if
the interrupt is not required to be serviced by CPU, the flag can be read through RMR register. And
this flag is cleared when the interrupt is serviced, RDPE bit is cleared or software writes ‘0’ to the bit
position.
11.7.8 Examples of Carrier Signal Selection
The next table shows examples of selecting carrier signal according to CFRH and CFRL registers for
two kinds of carrier clocks.
